ISO 4897 Cellular Plastics - Determination of Coefficient of Linear Thermal Expansion of Solid Materials at Lower Ambient Temperatures

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 4897 testing. This standard is cellular plastics at lower ambient temperatures with the coefficient of linear thermal expansion of the solid.

ISO 4897 Cellular Plastics - Determination of Coefficient of Linear Thermal Expansion of Solid Materials at Lower Ambient Temperatures

The temperature chosen, which is more representative due to the preferred method as it gives a value on a large sample, the anisotropy of the material or product, etc. In practice, difficulties may be encountered in controlling it correctly. Homogeneity of low temperature inside the test chamber Temperatures below -70 OC. Should this be the case, it should be used to obtain an "average" coefficient. Temperature for the temperature range between cryogenic and ambient temperature.

The values ​​obtained in these tests are only valid measurements. It is for the specific sample being tested at the time being tested. They cannot be applied to a product in general and cannot be used to predict. It is the performance of the same material at a future date. Care should also be taken in applying the value obtained in this study. They are products of which the tested material is a part to calculate the overall coefficient of expansion of the composite. Many solid cellular products are not isotropic. This is usually attributed to the fact that the cells in the material are elongated. a particular direction. This direction methods as this “direction of anisotropy”. Tests conducted in this aspect give different results than those normally obtained. The direction of anisotropy varies within a product and therefore the number of test samples required for product specification is usually given in this International Standard.
